3-6-2. Installing the Ceiling Panel

After completing the wiring process, install the supplied wiring cover before installing the panel.

It is not possible to install the wiring cover after install- ing the panel.

The power must be turned ON in order to change the flap angle. (Do not attempt to move the flap by hand. Doing so may damage the flap.)

(1)Insert the temporary fasteners (stainless steel) on the inside of the ceiling panel into the square holes on the unit to temporarily fasten the ceiling panel in place. (Fig. 3-20-1)

●The ceiling panel must be installed in the correct direction relative to the unit. Align the REF. PIPE and DRAIN marks on the ceiling panel corner with the correct positions on the unit.

●To remove the ceiling panel, support the ceiling panel while pressing the temporary fasteners toward the outside. (Fig. 3-20-1)

(2) Align the panel installation holes and the unit screw

holes.

(3)	Tighten the supplied washer head screws at the
	4 panel installation locations so that the panel is
	attached tightly to the unit. (Fig. 3-20-2)
(4) Check that the panel is attached tightly to the
	ceiling.

●At this time, make sure that there are no gaps between the unit and the ceiling panel, or between the ceiling panel and the ceiling surface. (Fig. 3-21)

●If there is a gap between the panel and the ceil- ing, leave the ceiling panel attached and make fine adjustments to the installation height of the unit to eliminate the gap with the ceiling. (Fig. 3-21)
